Well with a POD of 1917 alone it's tough to join an Analog. First and foremost all factions save the Bolsheviks were for continuing the war with Germany, despite the problems of doing so. Second even if Russia somehow makes it out of the war, it has to deal with all the aforementioned factions, hope they don't come to blows in a civil war. All of this is on top of trying a stable social situation. Then there's the issue of what would they do with all the various Non-Russian populations in the Russian state.
This is isn't even getting into, how is this NATO/EU analog going to form?
I said this upthread, but one way (and I have no idea how plausible this is) is to have Russia and Germany flip roles in an alternate WW2. Germany goes Red instead of Fascist, along with a few other countries (say Poland, Austria, etc.), while the Whites win the Civil War and turn into something halfway between Fascist Italy and Germany, with a virulent hatred of Communism.
*Russia gets it into its head that it needs to reform "Great Russia", and so they start making moves on Eastern Europe. They invade Poland, Germany fights back, and somehow you get the US/UK/France/etc. in the picture. *Russia is defeated, and is on the receiving end of a Marshall Plan like reconstruction effort, as Germany (and their Warsaw Pact analogue) are now a major power right in the middle of Europe.
Like I said, no idea if this is possible, but it's something, I guess?
